I didn't look at this mechanism until now, but it appears from the
Samsung datasheet that any of the EINT[15:0] interrupts can wake from
what they call "SLEEP", ie, CPU powered down.
One of the motion sensors interrupts maps to this range (the "top" one
on GPF0 --> EINT) and one doesn't (the bottom one on GPG8 -->
If I understood it then you could probably do something with that if the
idea is shaking it awake or so on.
